This innovative component is used to secure cord and keep beads from sliding around. The stringing hole is lined with a stretchy silicone rubber, which enhances its ability to hold beads in place and limit the movement of charms. This highly functional element will add the perfect finishing touch to your most sophisticated designs. It features a ring of icy blue crystals around the blue epoxy base.
